We're using the Lunati 243/251 @ 0.050 hydraulic roller. It seems to have worked very well. The engine could use more cylinder head but Edelbrock sponsored us for the build so we used what we were given. The heads were given a clean up and flowed about 450hp.
NICE!
For being 150 cfm down on the carb tests, the Edelbrock did very well. It appears that the torque line did not dip as much in the beginning. Am I correct?
Also, how much if any vacuum did the Edelbrock pull?
The Edelbrock carby impressed the hell out of me. The curve was beautiful and smooth and the more we leaned it out on the secondaries the more power it made. We actually ran out of jet. It was pulling 2.8inches on that video run, we did try a two-inch spacer (to even it up with the Holley) and it made another 7lb/ft but no more horsepower, and it was pulling 2.6inches on that run.
It'll be a great street engine.
Originally we approached Edelbrock about this deal because we wanted to use their Victor heads but no one could give us a date as to when they would be ready. They were a little hesitant to supply the Performer RPM heads because they weren't sure that they would hit out 500hp target but decided to take the punt and it's worked out nicely.
Not bad for a hydraulic cam, dual plane, pump gas small block Chrysler. The winner of this car is going to be very happy.
